Non-contrast enhanced MR angiography of coronary artery is a promising imaging method. In this study, the image quality of two non-contrast enhanced coronary MRA imaging methods were compared, included 3D-mDIXON and 3D-TFE-WHCA. 3D-mDIXON and 3D-TFE-WHCA showed good image quality with high SNR, and 3D-TFE-WHCA showed improved CNR and higher score in vascular display quality. According CTA data, T1-TFE-BB demonstrated the coronary vessel wall as medium high signal with regular margin and good contrast with the fat around the coronary artery. Combination of 3D-TFE-WHCA and T1-TFE-BB can be used as the imaging research method of coronary atherosclerosis.
